Authentication Device Dynamic Order Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle anti-theft device experiences increased authentication time when used by unauthorized individuals due to inefficient authentication ordering.
Innovation Solution
The authentication device prioritizes the first registered person from the last session and the second registered person authenticated by another device, placing them first and second in the authentication order to enhance the probability of successful authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If authentication is performed in a fixed order without prioritizing registered persons, then the authentication process is simple to implement, but authentication time increases when unauthorized individuals attempt authentication
Solution Approach 1:
The system performs preliminary actions by storing last session information and authentication order information before authentication is needed. The control unit retrieves previously authenticated person information and pre-establishes an optimized authentication order, so that when authentication occurs, the system can immediately proceed with the pre-determined efficient order rather than calculating it in real-time
Solution Approach 2:
The authentication order is made dynamic rather than fixed. The control unit adjusts the authentication order based on stored information about previously authenticated persons and current session context. This dynamic adjustment allows the system to prioritize likely authenticated users, reducing authentication time while adapting to different usage scenarios
2Productivity
If the authentication order is dynamically adjusted based on last session information, then authentication efficiency is improved, but the system complexity increases
Solution Approach 1:
The information storage is segmented into distinct functional units: last session information storage for storing previously authenticated person data, authentication order information storage for storing the optimized authentication sequence, and registered person information storage for storing all registered user data. This segmentation allows each storage unit to have a specific, simple function while collectively providing sophisticated authentication optimization
Solution Approach 2:
The control unit acts as an intermediary that manages the complexity of coordinating multiple storage units and adjusting authentication orders. It retrieves information from various storage portions, processes the data to determine optimal authentication orders, and executes the authentication process. This intermediary role centralizes the complexity management, keeping the overall system architecture clean and maintainable

AI summary
An authentication device includes a last session information storage portion that stores data of a first registered person successfully authenticated in the last session, an input unit to which information of a second registered person successfully authenticated by another authentication device is input, an information acquisition unit that acquires identification information of a user via an information sensor, a registered person information storage portion that stores registered person information in which a plurality of registered persons including the first and second registered persons are associated with their registration identification information, an authentication order information storage portion that stores information about an authentication order of the registered persons, and an authentication unit that authenticates the user by comparing the identification information acquired from the information acquisition unit with the registration identification information stored in the registered person information storage portion according to the stored authentication order.
